OpenRules allows business users (subject matter experts with no programming experience) to create, test, and maintain operational decision models using only Excel (or Google Sheets) as an editor. Business analysts can use develop and deploy their own business decision models while modifying OpenRules models with their own variables and rules.
Usually a decision model is used to determine certain business goals and subgoals specified in the table “Glossary”. The business logic of these goals/subgoals is defined by various decision tables. The book “Goal-oriented Decision Modeling with OpenRules” provide very simple guidelines for creation of business decision models which you can freely available for download, modify, and test.
